Perhaps the first post in this thread should include links to previous topics where the question was asked, and add as many past topics as possible, e.g.:
Latest Mame Versions - 
Possibly
Bittorrent Clients - 
Definitely (Transmission, Deluge, etc)
Sega Saturn Emulator - 
Highly Unlikely
GP32/GP2X Emulator - 
Possibly (or ports where possible)
Urban Terror - 
Impossible (Closed Source Extensions)
Itunes - 
Impossible (Closed Source)
Spring RTS - 
Possibly
I only went back a few pages and wasn't very thorough, but you get the idea. 
 
EDIT: Also perhaps try to link to the first time it was asked, to avoid "Use the search function!!!", for people who are actually reading the stickies
